为了探讨问荆对大豆生殖后期生长的化感效应，采用温室盆栽法，研究问荆夏枝水浸液对‘北豆42’(BD)、‘北交8032’(BJ)、‘登科1号’(DK1)、‘登科3号’(DK3)和‘黑河43’(HH)5个品种大豆生殖后期形态、生理指标及产量性状的影响。结果表明，问荆水浸液处理后，各品种大豆的株高、叶面积、叶绿素含量、单株粒数、单株结荚数、有效结荚数、结荚高度都降低；MDA含量、WSS含量增加，过氧化氢酶活性、过氧化物酶活性先升高后降低。‘北交8032’在0.04 kg/L、0.07 kg/L问荆水浸液处理后产量性状的株高显著降低(P<0.05)，‘北豆42’在0.07 kg/L问荆水浸液处理后节数显著降低(P<0.05)，其他品种大豆最终株高、节数变化较小。[结论]说明在低浓度问荆水浸液下大豆有一定的抗性，但是问荆的化感效应对大豆生长有很大影响。

Our objective was to discuss the allelopathy of Equisetum arvense L. on soybean at postreproductive growth. The greenhouse pot experiments were performed to investigate the effect of E. Arvense sterile shoots aqueous extract on morphological indices, physiological indices and yield trait of 5 kinds of soybeans, i.e., BD, BJ, DK1, DK3 and HH in postreproductive period. The results showed that plant height, leaf area, chlorophyll content, grain number per plant, pod number per plant, effective pod number per plant and podding height of all kinds of soybean decreased, POD activity and CAT activity firstly increased and then decreased with E. arvense aqueous extract treatment. The plant height in yield trait of BJ significantly decreased with the treatments of E. arvense aqueous extract at 0.04 kg/L and 0.07 kg/L concentration (P<0.05). The pitch number of BD significantly decreased with the treatments of E. arvense aqueous extract at 0.07 kg/L concentration (P<0.05). However plant height in yield trait of BD, DK1, DK3, HH and pitch number of BJ, DK1, DK3, HH changed little after the treatment of E. arvense aqueous extract. All of above indicated that soybean had certain resistance with the treatments of E. arvense aqueous extract at lower concentration, while there was great influence of the allelopathy of E. arvense on soybean at postreproductive growth.
